JAN2N2920A

Overview

The JAN2N2920A is a military-grade dual NPN bipolar junction transistor (BJT) array manufactured by Microchip Technology. It features a TO-78-6 metal can package designed for through-hole mounting. The device supports a maximum collector-emitter voltage of 60V and a continuous collector current of 50mA, with a power dissipation rating of 350mW. It operates within an extended temperature range from -65°C to +200°C junction temperature. Key electrical characteristics include a DC current gain (hFE) of at least 300 at 1mA and 5V, and a collector cutoff current of 10µA maximum. The component complies with MIL-PRF-19500/355 specifications.

Feature Summary

• Dual NPN configuration housed in a hermetically sealed TO-78-6 metal can package
• Qualified to MIL-PRF-19500/355 military standards for high reliability
• Extended thermal capability supporting junction temperatures up to 200°C
• High DC current gain ensuring efficient signal amplification

Applications

• Military aerospace electronic systems requiring radiation-hardened or high-reliability components
• Harsh environment circuit protection and switching applications
• Precision analog signal processing in defense instrumentation

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm compliance with MIL-PRF-19500/355. Ensure the supplier provides valid traceability records and certification of conformance. Confirm that the TO-78-6 package integrity meets military handling requirements. Cross-reference the manufacturer part number with authorized distribution channels to avoid counterfeit components.

Selection Notes

Select this component when a dual NPN topology is required in a ruggedized metal package. The 60V breakdown voltage suits moderate voltage switching tasks. Verify that the 50mA current limit aligns with load requirements. Consider the TO-78-6 footprint constraints during PCB layout. Evaluate thermal management strategies given the 350mW dissipation limit in enclosed military enclosures.

Part Context

The JAN2N2920A belongs to the JAN series of dual transistors produced by Microchip Technology under strict military quality controls. It serves as a direct replacement for legacy dual NPN arrays in established defense designs. The TO-78-6 package provides superior thermal conductivity and environmental sealing compared to plastic alternatives. This series is integral to maintaining supply chains for long-life military hardware.

Replacement Considerations

Direct equivalents may include other MIL-PRF-19500/355 qualified dual NPN arrays in TO-78-6 packages. Verify pinout compatibility and electrical parameter margins before substitution. Check for updated manufacturing notices or lifecycle status changes from the original equipment manufacturer.
